limit as x approaches 0 of (6^x-4^x)/x

x \to 0 lim (\frac{6 ^{x} - 4 ^{x}}{x})

ln (6) - 2 ln (2)

Decimal Notation

0.40546 \dots

Solution steps

x \to 0 lim (\frac{6 ^{x} - 4 ^{x}}{x})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{6 ^{x} ln ( 6 ) - ln ( 2 ) \cdot 2 ^{2 x + 1}}{1})

= x \to 0 lim (\frac{6 ^{x} ln ( 6 ) - ln ( 2 ) \cdot 2 ^{2 x + 1}}{1})

Plug in the value

x = 0

= \frac{6 ^{0} ln ( 6 ) - ln ( 2 ) \cdot 2 ^{2 \cdot 0 + 1}}{1}

Simplify

\frac{6 ^{0} ln ( 6 ) - ln ( 2 ) \cdot 2 ^{2 \cdot 0 + 1}}{1} : ln (6) - 2 ln (2)

= ln (6) - 2 ln (2)

\int - x^{2} \frac{3}{3} d x

\frac{d}{d x} (x tan (y))

\int_{0}^{2} \frac{1}{x ^{2} + 4} d x

\frac{d}{d x} (e^{i 2 x})

f (- 5) = x + 6
